10/11kV Industrial Oil Immersed Transformer for Electrical Substation

Overview of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Specifications of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

This transformer powers industrial sites and substations. It steps down high voltage electricity. The main voltage ranking is 10kV or 11kV. The secondary voltage matches your specific devices demands. We construct it tough for demanding industrial settings.

The core utilizes state-of-the-art grain-oriented silicon steel. This lessens power loss during procedure. Copper windings guarantee reliable power transfer and resilience. The entire active assembly sits inside a durable steel storage tank. The storage tank is filled with high-grade insulating mineral oil.

The oil does 2 major tasks. It cools down the transformer properly. It likewise gives vital electric insulation inside. This style is known as Oil Natural Air Natural (ONAN). Heat climbs naturally via the oil. Then it dissipates from the container’s surface into the air. External radiators enhance the air conditioning surface area. This deals with higher loads securely.

Defense is essential. The tank consists of a conservator tank. The conservator holds additional oil. It enables oil expansion as temperature levels change. A rest with silica gel maintains moisture out of the oil. A Buchholz relay identifies interior faults. It causes an alarm or shuts the transformer down. Stress alleviation devices prevent dangerous container overpressure. These attributes secure the transformer and your employees.

We build according to rigorous international criteria. Usual standards include IEC 60076 or IEEE C57.12.00. Every device undergoes rigorous manufacturing facility testing. This consists of ratio checks, winding resistance tests, and insulation resistance checks. We perform induced voltage examinations and used voltage examinations. We measure tons loss and no-load loss exactly. Temperature increase examinations confirm cooling efficiency. Impulse examinations confirm strength versus voltage rises. This screening guarantees safety and security and integrity. You get a transformer prepared for long-lasting solution.

Applications of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

Industrial oil-immersed transformers rated 10/11kV are essential tools for electrical substations. They take care of the essential task of voltage change. Substations get power at high transmission voltages. These transformers tip that voltage down to more secure, usable degrees like 10kV or 11kV. This stepped-down power is then dispersed successfully to factories, plants, and large facilities nearby.

Their durable oil-immersed style makes them excellent for requiring industrial setups. The shielding oil inside serves 2 vital objectives. It cools down the transformer windings successfully during continual hefty procedure. It also offers excellent electric insulation, preventing harmful brief circuits. This dependability is important for substations sustaining essential commercial processes.

You locate these transformers directly inside devoted substation structures or safe outside rooms. They develop the core web link between the high-voltage grid and the regional industrial power network. Their primary feature is dispersing the stepped-down power reliably. They feed power straight to huge electric motors, hefty machinery, and substantial plant-wide electrical systems within manufacturing facilities, mines, or handling plants.

These transformers are constructed hard. They deal with the consistent, heavy electrical loads typical in market. The oil cooling system takes care of the substantial warm generated. This makes sure steady procedure night and day. Their design focuses on long life and very little downtime. This is critical for commercial operations where unanticipated power loss suggests significant production stops and monetary loss. They offer the steady, reputable power foundation industrial facilities definitely need.

5 FAQs of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

Here are five common questions about 10/11kV Industrial Oil Immersed Transformers for electrical substations:

What does this transformer do?
This transformer changes electricity’s voltage level. It steps down the high voltage electricity coming into the substation. It makes the voltage safe for factories or large buildings to use. It powers heavy machinery and equipment reliably.

Why use oil inside it?
The transformer core and windings sit inside special insulating oil. This oil does two main jobs. It cools the transformer parts during operation. It also provides vital electrical insulation. Oil cooling handles large power loads effectively. It keeps temperatures stable.

What are its main features?
These transformers are built tough for demanding industrial sites. They use strong steel tanks holding the oil and internal parts. Radiators or cooling fins attach to the tank. They help dissipate heat. Robust bushings safely bring the electrical cables in and out. Protective devices monitor oil levels and temperature. They give warnings if problems happen.

Is it safe?
Safety is a top priority. The transformer tank is completely sealed. This prevents oil leaks. Modern designs often include pressure relief devices. These protect the tank if internal pressure builds too high. Fire walls or special pits around the installation add extra safety. They contain any potential oil fire. Regular testing ensures it meets strict safety standards.

How much maintenance does it need?
Oil immersed transformers need regular professional checks. Technicians test the oil quality often. They look for moisture or chemical breakdown. They inspect the physical condition of the tank, bushings, and cooling surfaces. They check all connections are tight. They confirm protective devices work correctly. Keeping the transformer clean and dry is also important. Proper maintenance extends its working life significantly. It prevents unexpected failures.
